The IcedTea project provides a harness to build the source code from OpenJDK using Free Software build tools, along with additional features such as the ability to build against system libraries and support for alternative virtual machines and architectures beyond those supported by OpenJDK.

This release begins our OpenJDK 8 support with the first release based on OpenJDK 8 u77.

There are still some remaining issues with OpenJDK 8 support in the alternate virtual machines, JamVM and CACAO. Both will build against OpenJDK 8 but the resulting virtual machine crashes. We hope this will improve with time, but for now, we recommend sticking with HotSpot, and thus the use of the zero-assembler projects for those architectures yet to have a native port.

This release updates our OpenJDK 7 support in the 2.6.x series with the March 2016 interim security fix from OpenJDK 7 u99.

Please Note: The fix for S8086092 below affects the build of the in-tree copy of LCMS. If the default of using the system LCMS is used, this will not take effect. Users should either switch to in-tree LCMS or (ideally) apply the fix to the system build of LCMS.

This release updates our OpenJDK 6 support in the 1.13.x series with the July 2015 security fixes.

Please Note: This release includes a backport of jdk.tls.ephemeralDHKeySize which changes the default for Diffee-Hellman ephemeral keys to 1024-bit (CVE-2015-4000). To use the previous default (768-bit keys), pass -Djdk.tls.ephemeralDHKeySize=legacy on the command-line. All current releases of IcedTea 1.x and 2.x, along with OpenJDK 8, allow the use of “matched” mode which creates an ephemeral DH key matching the size of the authentication key, or the specification of an explicit key size between 1024 and 2048 bits inclusive (e.g. -Djdk.tls.ephemeralDHKeySize=1536).

This release updates our OpenJDK 7 support in the 2.5.x series with the July 2015 security fixes. This is the last release in the 2.5.x series.

Please Note: The backport of jdk.tls.ephemeralDHKeySize now defaults to 1024-bit keys (CVE-2015-4000). To use the previous default (768-bit keys), pass -Djdk.tls.ephemeralDHKeySize=legacy on the command-line. Both OpenJDK 7 & 8 allow the use of “matched” mode which creates an ephemeral DH key matching the size of the authentication key, or the specification of a key size between 1024 and 2048 bits inclusive.
